![]() The format was developed by and for APCO and is licensed from them. A later version of Type 2 trunking, called APCO P16, used the same Type 2 control data but allowed either analog or digital modulation.ĪPCO P25, as we discussed last week, is an all-digital format sold by several manufacturers, including Motorola, Harris and others. ![]() Some Type 1 systems were upgraded, either to Type 2 or to a hybrid system that allowed both Type 1 and Type 2 radios, this was commonly referred to as Type 2i.

Motorola developed what was called Type 2 trunking that used a similar 3600 baud control data signal but removed the restrictions about Fleets and Subflleets and removed many of the limits on radios. In time it was found to be too limiting, it restricted the number of subfleets and radios that could be accommodated within the Fleets. The original Type 1 systems used a 3600 baud control data signal and a Fleets/Subfleet programming style. “Motorola” trunking systems include Type 1, Type 2 and Type 2i systems.
